Answer:

-13/400

Step-by-step explanation:

The pertinent formula is

                             change in f(x) over [a, b]        f(8) - f(0)

a. r. of change = --------------------------------------- = ----------------

                              change in x over [a, b]               8 - 0

Continuing these calculations, we get:

                               2(8) - 2              2(0) - 2        14/8           -2/8

                     (1/8) -------------- - (1/8) ------------- = -----------  -  -----------

                                5(8) - 6              5(0) - 6       40 - 6           -6

                         

                                                                                7/4       1/4

This simplifies to    average rate of change =      ------- - --------

                                                                                  34         6

                                                                                    7                 1

                                                                          =   ------------- - ---------- = -13/400

                                                                                   136             24

What type of spectrum is produced when electromagnetic radiation is emitted or absorbed as electrons change energy levels in an
DerKrebs [107]

Answer:When electrons in atom interaction with light or photons one of the two process takes place:

1) they can absorb photons of a characteristic wavelength (which depends on the energy difference between two interacting atomic levels) and get excited to a higher energy level

2) or they can jump to a lower energy level and emit photons of the corresponding wavelength.

The type of spectrum produced when electrons in an atom undergo transitions to various levels by absorbing or emitting photons is termed as atomic spectrum.

What statement is true by the ASA postulate
egoroff_w [7]
By the ASA postulate we figure that:
Angles C and D are equal (noted by the line through these angles)
Lines CB and DE are parallel and equal in length (noted by the double line through these sides)
Angle B and E are both 90° (noted by the square at each of these angles)

From this information, we can say that triangle CBA = triangle DEA is true.
